We need to see the purpose of this - when we using the socket at the server side we need to advertise to the rest of the world (read client) so that client can connect to it to specific IP and port, whereas there is no such requirement at the client side. That is the reason Server has to bind to a specific address and to listen a specific port.

As per my understanding Receive system calls will be a blocking call of the code... it will not go ahead unless it receives the response from client .. my question is how would i set time in that? i want my code should wait only for few seconds then it has to come out from that

Is it right that it is used to bind Port number with IP?
If it is, then What is the need of binding it? and Why it is not present in UDP?
And also, What is the use of listen(5) ?
Does it mean that server can be connected maximum to 5 client? or it means that if server is busy with other client then 5 more client can be in queue.?
and also, What is the use of select() ?
As far as i know it is used when we want to monitor continuously input/output for that particular file descriptor.
is it correct?
If yes, then why it is used only when accepting connection request from multiple client.?

For An Example:
I have Socket-Programming where server is connected to 5 clients and it continuously sends and receives to all the clients.
Now, If one of the client looses the network or in whatever the case one of the client fails then master will also fail and because of it all other client will also be failed.
